Thanks, this was a good explanatory article on the issue of NOX. NOX from power plants is regulated, as it happens. But it is also a by-product of hydrocarbon production...such as cars. The single biggest cause of smog in major cities (excluding those in India and China though increasing there too) is automobile pollution. The article was worth the read.
